Problems With GPL & OpenGL

I recently got a new PC and decided to give GPl another go after a 2 year
hiatus from sims.  When i pick OpenGL the screen flickers like crazy.  Can
anybody sugest what to do?  Also I used to have a link to a site that was
reduing all the cars, can someone point me to that site?

Thanks.

I'd ask this question in rec.autos.simulators.  Lots of *** GPL'ers there
:-)

Oh, duh..  This is RAS :-)  Thought I was looking in an OpenGL group.

   WHY bother with opengl anymore?   The differences between dx9 and opengl
are not that great...and dx9 can certainly do things opengl cannot.

just curious..

I'm guessing Open GL is still a big hit with the anti-Microsoft folk...

For car updates go here: www.gplea.com

For screen flicker I'm guessing you mean the refresh rate? Depending on
your graphics card there are various fixes to the Win2k/XP 60Hz bug, I
use rivatuner with my nVidia card but there are Ati solutions too. This
isn't a problem with gpl, it's a problem with Windows.

If you are talking about the image being distorted in-car could you
describe the problem in a little more detail & tell us some of your
system specs? Graphics Card, OS etc.

folk...

Nothing to do with Microsoft, I don't get the font corruption or
'melting menus' (with AA) in OpenGL. It allows me to run gpl in a window
too in a way that suits my needs.

Because, at least in my experience when I had a GF4Ti4200, OpenGL
looked better and felt smoother.
There were a few tweaks to make it run better (like you had to use 4xS
if you wanted FSAA).  Best place to look is probably forum.rscnet.org.
If the OP doesn't have an nVidia card, don't bother.  I don't think
the updated OpenGL renderer worked with anything else.

HTH,

Dave, GPL has absolutely zero features from anything beyond DX7, so DX9 is a
pretty ridiculous statement to make about GPL.  nVidia cards are known to
run faster in OpenGL, in pretty much all the Papy titles, and with teh
correct settings, the video quality should be virtually identical.

There's an updated OpenGL rasterizer at
http://forum.rscnet.org/showthread.php?t=49101 if you haven't gotten
that already.  I find that on my system (P4-2.4 GHz, GeForce4 Ti4400),
OpenGL is no better for image or framerate, except that the fonts
don't corrupt (fix for that in D3D is to go to the replay full screen
and select the Pitlane Camera) and I don't use FSAA (I'm at 1600x1200
res)

I guess I want it all, I run 1600x1200 with 8x Aniso & 4xAA ;-)

I found my old Gf4200 would run36fps at 1152x864 with 4xAA or 1600x1200
with no AA, my Gf5900 runs 36fps with the above settings fairly
comfortably. CPU is an XP3000.

Some graphics cards will throw a hissy fit in OpenGL but be fine in D3D.
nVidia cards will generally work better in OpenGL with gpl, but it's
subjective.

   true true about dx7 and GPL.  But I figured just about everyone would
be up to dx9 by now...  
  :)  I guess that could be another question...!!  lol

OpenGL is more portable (there is a Linux implementation, for
instance). Thanks to this fact there are native Linux clients for
quakeIII, Unreal Tournament (2003) and friends, so you don't have to
resort to WINE or WINEX if you want to play these games in Linux.

Cheers,

uwe

OpenGL is also a lot easier to write stuff with :-)
